"Chicken of the woods"?

I was trying to identify a large mushroom growth I found at the base of
an oak tree.
The best I can guess after looking through many books and websites, is
that it is Laetiporus sulphureus, or Polyporus sulphureus: "chicken of
the woods".
Whatchy'all think?
(sorry about the poor scan - I wanted to protect the scanner platen
glass from the dirt and stuff)

How best to store it? Fridge? Sliced and dried?
How would one go about propagating such a mushroom? Comprimise the bark
of the appropriate species tree and stuff some mushroom into it?
Also:
I had collected a bunch of other mushrooms for identification, and
noticed that there were a bunch of tiny white worms emerging from what I
tentatively identified as Marasmius oreades, the "fairy ring mushroom".
(Of course, it could be damn near anything else for I know. They were
brown/yellow, gave a brown spore print, grew in a ring in the grass near
some small planted trees, and had gills broadly attached to the stipe -
the kind of gills where not all of them are attached to the stipe.
I'll try to get a scan of the ones I dried out at 37 deg C. )
Anyway, how do most people 'debug' their mushrooms, either for sample
preservation or as preparation for eating?
Thanks for helping a fledgling mycologist/mycophile/mycophage :)
